A communication electronic device which comprises a grounding element and a slot antenna is provided. The slot antenna is formed by a feeding element, a first slot, a second slot, and a third slot. The first slot is an open slot, which has an open end at the first side edge and a closed end extended toward the interior of the electrical conductor. The second slot is an open slot, which also has an open end at the first side edge and a closed end extended toward the interior of the electrical conductor. The second slot is substantially parallel to the first slot and is closer than the first slot to the grounding element. The third slot is a closed slot, whose two closed ends are all in the interior of the electrical conductor. The third slot is aligned between the first slot and the second slot. |
